In this video I’ll focus on creating App Inventor interfaces. I’ll take the vector art I made in the last tutorial and convert it into a App Inventor interface.
I create regular non-App Inventor interfaces in pretty much exactly the same way. Here is the original vector art I created. Here is the finished transparent PNGs I made in this video. The component information follows the video. Continue reading Android Development for Beginners 12
Last year I did a big promotion for the Samsung Smart App challenge, so I thought it would be fun to take a look at who won and why they won. The main goal of those developers that participated was to develop apps specifically for the S4 device, but also to incorporate the Samsung Chord capabilities into those apps.
I am going to get the opportunity to ask one of the developers questions. Leave the questions you want me to ask below. Continue reading Samsung Smart App Challenge 2013

Here I’ll show you how I created the layout and I’ll also walk you through the techniques needed to draw all of your icons in Inkscape. The vector art is available here. Here is an Inkscape video tutorial if you’d like to learn more. Continue reading Android Development for Beginners 11
Here is my Spicy Bean Curd Recipe. I love this recipe because it doesn’t lose its wonderful flavor as you increase the heat in the dish. I also love it because it can be made in 10 minutes and it has many flavors and textures you don’t find in most meals. The Bean Curd (Tofu) is delicate and yet firm. The scallions have a nutty subtle bite. I really enjoy it.
This version is not very spicy, but feel free to double the amount of chili paste and ginger to increase the heat. Continue reading Spicy Bean Curd Recipe
In this tutorial I’ll walk you step-by-step through the process of using App Inventor to Parse JSON data. You have to watch the last tutorial to understand this one.
I’ll pull JSON weather data from Weather.gov and show how App Inventor organizes that data. I’ll then pull in specific data that we will use to create our Android weather app. I’ll also show you how to add padding to components in App Inventor. All of the blocks used can be found after the video below. Continue reading Android Development for Beginners 10
This is the first video in a series in which we will make a professional weather app for Android. In this video I will show how to parse JSON Data with App Inventor. I also cover the App Inventor Web component, using Location Sensor, converting JSON data into an App Inventor List and much more.
I pull all the weather data from weather.gov. If you want international weather data I’d use the JSON feed from the Weather Underground. All of the blocks follow the video. Continue reading Android Development for Beginners 9
In this video I present my Green Curry Eggplant Recipe. This is a very spicy recipe if you get a nice and spicy jalapeño. I loved this recipe so much that I had to find alternative ingredients that were available to me year round.
I’m sure this video will get some laughs because I have so many people from around the world watching these videos. I’d love to hear more about how I could make this dish and others in similar ways. I love to eat different food from around the world. The recipe follows the video below. Continue reading Green Curry Eggplant Recipe

Then we’ll put the toolbar together in App Inventor and use them to switch screens. The blocks used can be found after the video below. Continue reading Android Development for Beginners 8
In this tutorial I’ll show you most of what you need to know for drawing Android buttons for your interfaces. I’ll be using a free program called Inkscape to draw 6 buttons. I did my best to cover all of the most common techniques you will need in this one tutorial.
If you want to know more about Inkscape, I have an Inkscape Video Tutorial that goes over most everything you can do with Inkscape. Here is the finished vector art from this tutorial. Continue reading Android Development for Beginners 7
I have received numerous requests to make more cooking recipes so to day I’ll show you my cheese polenta recipe with mushroom sauce! I absolutely love delicious food that I can make quickly. It took me under 13 minutes to make everything you see in this video. Minus the 1 hour soaking time for the dried mushrooms. If you don’t have an hour then feel free to replace the dried mushrooms with another cup of what ever other mushrooms you have on hand.
When you make polenta like this it tastes amazingly rich. Then when we add the mushroom sauce that takes it completely over the top. The ingredients follow the video. Continue reading Cheese Polenta Recipe
In this tutorial I decided to make an Android Beat Box App. It could also be converted into a voice note app, or anything else that would benefit from being able to record and later play back sounds.
I’ll specifically cover how to use the Android SoundRecorder, Player, take another look at using list, teach more about logic and incremental programming. All of the blocks used can be found below after the video. The answer for the Reset Button homework is also down there. Continue reading Android Development for Beginners 6
I have been asked numerous times to show the App Inventor Java Code. So here is a zipped archive for all the class files. You can take those classes and easily open them with a program called JD GUI. There are versions of it for every OS.
I got the code pretty easily with 2 programs being the apktool and Dex2Jar. They can convert APK files into the class files most of the time. After you install them you issue the following commands in your terminal or command prompt: Continue reading App Inventor Java Code
